2 out of 5 eggsSpotty Performance

Pros: 4 Drive bays with small footprint.

Cons: Intermittent, frequent dismounts/remounts of HDDs (all drives simultaneously). Less commonly, the unit powers off completely.

Other Thoughts: Windows 7 x64P This unit houses four 3TB drives and is used for multiple daily backups of Premiere Pro scratch drives. It was purchased in 10/2014 and its behavior has been consistent from day 1. . It is connected to computer via USB 3.0. e-SATA has not been used. Connection is made to rear, on-board USB 3.0 port. Front USB 3.0 ports have also been used, but no change in behavior. Cables have also been swapped--again, no change in behavior.

Event viewer will sometimes report disconnects as "Controller Error". No errors are shown when the unit powers down.

I would not recommend this unit for anything other than temporary, trivial, backup.

1 out of 5 eggs

Pros: Nice physical construction

Cons: Intermittent USB 3.0 drops
Poorly placed power connection on side of unit
Poor support

Other Thoughts: The other reviews make me certain I could make this box work with a replacement board, which support could give me. I'm six business days into no email communication from support. I'm giving up and returning this. I took the gamble that Newegg was stocking the newer, functional units by now. That appears not to be the case. I suggest you give this unit a miss.

5 out of 5 eggsAwesome litttle enclosure

Pros: Its size is amazingly small for being able to hold 4 HDDs. there is also very good drive cooling, and the USB 3.0 threw put is very good. I have all 4 slots filled up and have made transfers from each drive simultaneously, each drive will achieve around 50MBs give or take depending on the size of the files; a lot of very small files will transfer slower than one really big one. I am really impressed. One last thing, the enclosure supports ESATA which is rather uncommon.

Cons: There is one kind of a big problem i found almost right away. If you are planning on using ESATA (I was) you need to make sure that the SATA port you are going to plug the enclosure into supports what is called Port Replication. Hint.... if you plan on using a ESATA port that is controlled by your Intel chipset your gonna have a bad day. Thankfully USB 3.0 is pretty fast. however Win 7 will not let you create a dynamic volume on a USB storage device. This means all the drives installed into the enclosure will be seen as seperate HDDs. You cannot create a spanned volume and make one massive HDD. Sata will allow for this

Other Thoughts: One side note, you do not need to fill all the drive bays to use the enclosure. you can just get 2 and then upgrade later.

4 out of 5 eggsGreat Little Box

Pros: I have had NO issues with this box since I have installed it back in Auguet. I am a huge fan of recycling slightly older hardware so I have 4 used 160GB HDDs in this and I have not had any problems. I have this attached to a modified Dell Precision 670 Serverand USB 3.0 is transfers are fast. I have not tested eSata. I am not using any type of RAID just each drive mounted as its own.

Cons: No Cons to list at this time.

Other Thoughts: Good box for the price.

4 out of 5 eggsReview Update

Pros: Better customer support this time around

Cons: No new Cons to report

Other Thoughts: This is my update to an earlier review. The first unit I bought 3 years ago had failed. It was a backplane PCB issue and I wanted to replace it. Initially i found their web tech support dismal and they didn't have a support phone number. I then tried to contact them through email. To my surprise they were responsive and they found a replacement PCB and sent it over to their Toronto office for me to pick it-up. So my out of warranty unit was fixed for $35 instead of going to garbage. I am happy with that so I increased my rating by one egg.

4 out of 5 eggsNewest Revision Is Very Solid

Pros: -Supports eSATA and USB 3.0
-Has large cooling fan that's adjustable or can run on auto
-Powers off or goes to sleep with power state of PC
-Fast I/O performance, even under heavy multi-drive load
-Has activity indicators for each drive in the enclosure to monitor performance

Cons: -Construction is cheap and plasticy
-Front cover is flimsy and if opened regularly, feels like it could break
-Fan can be noisy at higher speeds
-USB 3.0 performance can be spotty depending on the chipset you connect it to
-Phone support is poor and forums are staffed by someone for who English is not their first language

Other Thoughts: This type of box is only for users with a certain use case. If you're one of those like I am, it's a fantastic value. There have been a lot of horror stories about earlier revisions of this unit being unreliable, dying after a while and needing firmware updates that are hard to obtain. The unit I bought is the third revision and at least so far, all the issues seem to have been resolved. It currently has 3 drives in it running under almost 24/7 medium to heavy load and it hasn't so much as sputtered under USB 3.0. It's faster than the external USB docks I used to use and though it has a large fan, it's quiet if you run it on the lowest speed, which is all I've needed with 3 drives under load to keep it cool. That it automatically powers down with my PC is great as well. From what I can tell, MediaSonic's tech support is pretty poor but so far, I haven't needed it, nor has this revision of the unit needed a firmware update. I was initially nervous about buying this based on older reviews but I can confidently say this has been fantastic for me so far.

4 out of 5 eggsperfect for my needs

Pros: I just needed JOBD capability. I had no need for raid. I presently only have two 2GB HDD's installed , but they where recognized immediately and up and running. Unit turns off and back on again with computer...that's a plus. All LED's are blue which match my scheme.

Cons: Fan is too loud; even on low setting. It's louder than all 5 of my case fans put together. Will eventually install a better fan.

Other Thoughts: I am using the USB3 interface because using the eSATA only recognized my 1st drive despite my motherboard claiming my eSATA port supports port multiplier. Yes, I do have AHCI enabled in bios.

5 out of 5 eggsMakes a nice Media Server

Pros: Cheap. Appears to be well built. Works with Seagate and Hitachi 3 TB drives. the Porbox's onboard usb hub is recognized by my WDTV Live (3rd Gen).

Cons: Cooling fan somewhat noisy. JBOD only, no RAID. But for the price that's expected.

Other Thoughts: Bought this to use as an external media storage box for my WDTV Live (3rd Gen). Had been using four 3TB external drives thru an external usb hub previously. Installed the new 3TB drives into the probox. Hooked it up to a usb 3 port on my pc. Recognized all 4 drives (JBOD) with no problems on Windows 7. Very stable. I copied several TB's of data into the box with no drops.

After setup, I hooked the loaded probox to one of the usb ports on my WDTV Live. Like magic the 4 drives in the probox showed up as local disks and the WDTV was able to stream the files from the probox to the tv, including mkv files. But, after about 10 minutes the usb connection would be dropped. Tried it on multiple mkv files and they would drop eventually.

Went to the Mediasonic site to see if they had a firmware update for the probox. No such luck. Went to the WDTV Live site and found that my streamer box firmware was way out of date. Updated the WDTV firmware and have not had a dropped connection since. For my application (JBOD not RAID), this little jewel has worked out perfectly.

I have a Samsung F8500 plasma tv. Hooked the Probox into one of the usb ports and the TV's native OS displays all 4 drives individually and plays every file I have tried. Including both mkv and flac.

The only negative I have encountered is the noisy fan. It is not quiet. You do get used to it's presence and don't notice it eventaully. I opened up the probox case and inspected the fan, looks like a generic 100 mm case fan. No label or id visible. I was going to replace it, but now I'm used to the background hum. So I won't bother for now.

3 out of 5 eggsMediasonic HF2-SU3S2

Pros: Inexpensive compared to other options, Runs quiet, Looks good

Cons: - If it's not on a UPS and the power goes off, it does not turn back ON when power comes back (unlike the computer it is connected to), so if ran unattended, it must be on a UPS for continues operation.

- The electronic board (SATA backplane where the drives are connected to) is not replaceable. In fact it can be, as it's only held in place with 4 screws, had MediaSonic chose to sell the part separately. So if it fails you have the throw the whole unit away which is a shame and is wasteful.

- Mediasonic tech support (web forum) lacks professionalism and MediaSonic does not provide a phone number for support.

Other Thoughts: This is my second unit, the first one was a USB2 version (SU2S2) and lasted about 3 years before the SATA backplane gave up the ghost, Can't seem to get straight answers from them to my simple questions like "is a replacement board available". This time I bought the USB3 version and hoping that I can get a better service life from this one although I am not highly optimistic. Price is the primary motivation for me in buying this brand.
